Is 16 GB of RAM enough for CAD and video editing?

It is workable for 2D CAD, photo editing and 1080p video. Heavy 3D scenes, 4K multicam timelines and many browser tabs will push it into swap, so check whether the memory is soldered before buying.

How does the Core Ultra 7 255H compare with older ZBook chips?

The 255H has 16 cores and a dedicated NPU, so it is a clear step up from 12th- and 13th-gen H-series parts in multi-threaded work. Single-core gains are smaller, so older ZBooks remain usable for light tasks.

Does it have a dedicated graphics card?

This configuration lists only the Intel Core Ultra 7 255H, so graphics come from its integrated Arc-class GPU. That is fine for CAD viewports and video playback but not for GPU rendering or modern gaming.

Is the 4 TB SSD user-replaceable?

HP workstations typically use standard M.2 slots, so the drive can usually be swapped or upgraded. Confirm the slot count and whether the drive is self-encrypting before you plan an upgrade.

Expect the laptop, a power adapter and documentation. HP does not include a stylus or docking station with the ZBook 8 G1i, so budget for those separately if you need them.

Is it worth choosing over a consumer 16-inch laptop?

Yes if you need Windows 11 Pro, a fingerprint reader, business support and a large SSD. A consumer laptop gives you better battery life and a lower weight for the same CPU, but less storage and manageability.
